Find the unknown mass that is placed on the car to the left. The mass of the carts themselves, without the masses on top of them, is 500 grams.

In what direction does the medium move relative to the direction of the wave? explain.

Acar of mass m goes around a banked curve of radius r with speed v. if the road is frictionless due to ice, the car can still negotiate the curve if the horizontal component of the normal force on the car from the road is equal in magnitude to 101) a) mv2/r b) mg/2. d) mg e) tan[v2/(eg)]

Atomic nuclei of almost all elements consist of
